Answer:
z = 31
Step-by-step explanation:
A triangle adds up to 180 degrees
Therefore this equation is formed: 61 + 3z + z -5 = 180
Simplify:
4z = 124
z = 31
Answer:

<h3>QUESTION-1:</h3>
we are given the center and the redious of a circle equation
remember that,

where (h,k) is the centre coordinate and r is redious of the circle
given that, h=-2 , k=-5 and r=1
Thus substitute:

simplify:

<h3>QUESTION-2:</h3>
Likewise

given that,h=7,k=-3 and r=√7
substitute:

simplify:

Answer:
First expression 8y +4x +10
Second expression 7x-3y +6
If you want to combine both expressions: 5y +11x +16
Step-by-step explanation:
Like terms are the terms which have same variables and powers/roots.
Example: 7x and 2x are like terms because the variables are both "x". So we can combine in 9x
In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same
10y + 3x + 10 + x -2y
10y-2y=8y 3x+x=4x
so 8y +4x +10
3x - y + 4x + 6 - 2y
3x+4x=7x -2y -y = -3y
so 7x-3y +6
